Tiana has already taken 1 page of notes on her own, and she will take 1 page during each hour of class. In all, how many hours w

Novosadov [1.4K]

Answer:

<u>42 Hours.</u>

Step-by-step explanation:

As an equation where y is the total pages and x is hours of class:

y=1+1x since she started with 1 page and does 1 page per hour.

Setting the total pages she needs as 43 (y=43) we get:

43=1+1x

Subtract one on both sides

42=1x

The 1 doesn't need to be written so

x=42

Therefore, it'll take her 42 hours to write all those notes.

Which of the following is the discriminant of the polynomial below x^2+4x+5

steposvetlana [31]

Answer:

$\huge\boxed{\sf Discriminant = -4}$

Step-by-step explanation:

Comparing it with quadratic equation $ax^2 + bx + c = 0$ , we get:

a = 1 . b = 4 and c = 5

So,

Discriminant = $b^2-4ac$

D = (4)²-4(1)(5)

D = 16 - 20

D = -4

Hence,

Discriminant = -4

$\rule[225]{225}{2}$

Hope this helped!

What is a21 of the arithmetic sequence for which a7=−19 and a10=−28? A. -35 B. 35 C. -58 D. -61

shepuryov [24]

Answer:

a21 = -61

Step-by-step explanation:

$a_{n}=a_{1}+(n-1)d$

$-19=a_{1}+(7-1)d$

$-28=a_{1}+(10-1)d$ (subtract to eliminate a₁)

9 = -3d

d = -3

-19 = a₁ + (6)(-3)

-1 = a

a21 = -1 + (21 - 1)(-3)

= -61
